<pre class="brush: java;">
import com.gf.key.TraceHandlers;
import com.gf.extra.trace.Trace;

Engine engine = new Engine();
engine.setConfig(TraceHandlers.class, true); //enable tracing
...
SomeAction someActon = new SomeAction();
engine.invoke(someActon);
     
Trace trace = TraceHandlers.getTrace(someActon); //get trace info from the action
</pre>
